Monocrystalline solar panels

Mono crystalline and polycrystalline solar panels side-by-side comparison.

About 80 percent of all solar panel installations consist of monocrystalline solar panels. Thus, this is by far the most popular solar panel today. The main reason is that monocrystalline solar panels have a higher efficiency than any other solar panel on the market.

There are other advantages to this type of solar panel and here you can read what exactly they are. Furthermore, you can find out all kinds of other interesting information about monocrystalline solar panels.

What exactly is monocrystalline?

The best way to explain what monocrystalline solar panels are is to explain the manufacturing process. Solar cells consist of silicon and this is first liquefied. A stick is dipped into the liquid silicon and it is slowly brought to the surface.

As the stick is pulled out of the silicon, the material adheres to the stick and forms into a round rod of silicon. After this, the crystals form a whole, which is why these solar panels are called monocrystalline. Slices are then cut from the silicon rod and these are the solar cells.

So you can immediately recognize the monocrystalline solar panels by solar cells with round corners. The polycrystalline solar cells, however, are straight.

The costs and characteristics of monocrystalline solar panels

The price for monocrystalline solar panels is higher than for polycrystalline. In return, you get a better yield. The higher costs arise because the production process as described above is more complicated and takes more time. From the table below you can get some facts about monocrystalline solar panels.

Differences in a nutshell

Color: Mono panels are mostly black, poly mostly blue. On a black roof, mono solar panels are therefore less noticeable.

Design: Mono panels can be recognized by the diamond-shaped planes between the cells, poly look more like a grid. With poly, the crystal planes are often clearly visible. Mono is more plain and also exists in all-black versions with some brands.

Yield: Mono panels can produce the same yield with a slightly smaller surface area. Also, mono performs slightly better in cloudy weather and worse in very hot weather because the panels get hotter.

Price: Mono tends to be just a bit more expensive than poly in general.

Conclusion: The main reason people choose monocrystalline or polycrystalline solar panels is appearance. In practice, the difference in yield and price cancel each other out.

The advantages and disadvantages of monocrystalline solar panels

Monocrystalline solar panels are the most widely installed solar panels today for good reason. As such, you can attribute more advantages to them than disadvantages, and the lists below reflect this well. You can use them to determine if monocrystalline solar panels are the best choice for you.

Advantages monocrystalline solar panels

The efficiency of monocrystalline solar panels is the highest of all types of solar panels. Some suppliers of high-efficiency solar panels sell them with an efficiency of nearly 23 percent and an output of 400 Wp. This makes it an excellent choice if you have a small roof but want to generate the highest possible efficiency.

The heat coefficient is better than polycrystalline solar panels. As a result, you lose the least efficiency with these panels if your roof is right in the sun.

Finally, monocrystalline solar panels are also often chosen because they are considered more beautiful. They have a dark color and this can be done completely black, with no aluminum frame. Therefore, this will make them much less conspicuous.

Disadvantages of monocrystalline solar panels

Monocrystalline solar panels are more expensive than polycrystalline solar panels. You can expect to pay about $50 to $100 more per panel. Producing monocrystalline solar panels involves more residual waste, which means it is a more environmentally unfriendly choice.

The heat coefficient is still quite high, especially compared to thin film solar panels that decrease 0.2 percent per degree above 25 degrees Celsius.

Are monocrystalline solar panels the best option for you?

You make the choice of the type of solar panel together with your supplier. They look at the situation on your roof and based on what they find there, you can then make a decision. Most people choose monocrystalline, however, because this is a fairly all-round solar panel.

Actually it can be placed on all roofs and especially if you have a limited area at your disposal this is the best choice. You make up the difference in price with polycrystalline because you need fewer panels.

If you want the best monocrystalline solar panels, choose a glass-glass version. These are much heavier and about 30 percent more expensive, but in the long run, glass-glass monocrystalline solar panels are the most profitable of all.

The efficiency is very high, the lifetime is extremely long, and the efficiency decreases significantly more slowly as the panels age. Because of this, the warranty arrangements are often considerably better as well. So with glass-glass monocrystalline solar panels you get the best solar panels available today.
